[WordPress]Gutenbergでカテゴリ、タグが表示されないetc

2019-05-23

対処法３パターン
・カスタム投稿タイプ、カスタムタクソノミーの設定で「show_in_rest = true」にする。
・index.php、.htaccessを適切に設置出来ているか確認する。
・DBを直接書き換えて下記のようなプロトコル、ドメインを含めないアドレスを設定している時、
投稿編集画面でtinymce.jsが読み込めていないため

WordPress アドレス (URL)「/manage」
サイトアドレス (URL)「/」

/manage/.htaccessに下記を追記する

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule ^manage/(.+)$ /manage/$1 [L]
</IfModule>
